In the event of severe drum wear, the play compensation system should be triggered by pushing the lug through a wheel mounting hole.

In the (rare) case of a detached and stuck jaw, you will need to use an extractor (A simple U-shaped 50x25 lgr 200 iron drilled to the Ø and center distance of the wheel fixings with a welded HM12 central nut can do the trick). If you do not have the means to manufacture this tool, you will need to use a specific extraction tool.
